TO ALL-WHOM I'l MAY CONOERN:

Figure 2 is a plan view of botto'm of the churn, showing space overwhich the lcatsE E'revolve, and steps for shafts D D'.

A is an iron shaft, provided with a crank, V, and two bevelled gears, BB', which runinto two bcvelled pinions, C C', (only being shown indrawings,) which are fastened to the two upright shafts D D', which runin suitable boxes or journals 'fitted into the-cover or the churn I andthe steps F F'. |Ihe shaftA runs in the boxes Gr G', which are properlyfitted `to the standard H H. Upon the shaft D D' are fitted the floats EE', which are held in place and caused to revolve by means of the brasssprings O O', which pass through the lower cross-pieces of floats, andinto a hole in the shaft D. There is a small hole in the pinions C C',for the purpose of receiving the end of the brass spring P P', therebyholding them from revolving when.

placing on the oats, when necessary to de so.

The churn is operated by turning the crank Z7, which, by means of' gearsB' B' and pinion C C', causes the {loats E E to revolve with greatvelocity. Further description, if. needed, in the caveat, tiled April,1867.
